 Technology – Is the processes and knowledge people use to extend human abilities and to satisfy human wants and needs

 Needs › Food › Water › shelter  Wants › Everything else Want - Goods or services not essential to survival Need – Goods or services that are essential to survival

 Communication  Energy and Power  Manufacturing  Construction  Transportation  Bio-Related Technology

 Is the devices and processes used to communicate.

 Energy – the ability to do work or make an effort.  Power – The measure of work done.  We have the ability to harness energy and power and use it to our advantage.

 Manufacturing – is the use of technology to make the things people want or need.

 Construction – is the design and building of structures.

 To Transport means to carry from one place to another. A transportation system is an organized way of moving goods and people using vehicles.

 Bio-Related Technology – includes all technologies with a strong relationship to living organisms, such as agriculture and health care.

 When you study technology you learn about how the world works.  It can help you understand the importance of our society › How should genetic engineering be used? › Stem Cells? › Fracking, Oil drilling? › Cloning???

 Helps you relate to other school subjects. › Mathematics – can become more relevant when you use it to calculate the velocity of a rocket › Social Studies – when you realize how advancements in technology bring about social and cultural change. › Science – scientific principles have more meaning when you can see them in action, like building a bridge.

 Technology has been around al long as the human race.  People had to find ways “invent technology” to solve their problems and meet their needs.  Technology continually evolves, the inventions themselves change, and so does the society from which they spring.

 As cultures evolved in different parts of the world, they developed technologies to help them. › Egyptians – discovered architectural forms that led to their great pyramids. › As we developed into an agricultural society we developed waterwheels. Waterwheels in turn lead us to a societal change where people decided that they did not need water wheels of their own. Instead, they could pay someone with a waterwheel to grind their grain.

 Inventions and Innovations › Inventions – New products or technologies. › Innovations – Altered Products or Technologies  Changes to a technology › Improves the quality of the product › Improves the efficiency of the process  Ideas may be shared across several technologies. › The design of the waterwheel evolved into the turbine.

 Goal Directed Research – Research performed to solve a specific problem. › Ex. Developing a drug for a specific disease.  Unexpected Results – Research performed for one problem may result in the solution to another. › Ex. Research performed on radar to detect submarines lead to the invention of the microwave oven.

 Every technology can be thought of as a system.  System – A system is a group of parts that work together to achieve a goal.  Parts of a technology system. › Input › Output › Process › Feedback InputProcessOutputFeed back

 Input – Resources that are put into the system  Seven input resources: › People › Information › Materials › Tools and Machines › Energy › Capital › Time

 In order to produce a device or process, people are needed to perform the operations. › Includes – Product designers, factory workers, sales people, etc…

 Any data or knowledge needed to make the system work. › Including – Scientific knowledge, assembly instructions, computer data, etc…

 All the things that make up a product. › Plastic, wood, metal  May be classified as either raw or industrial material. › Raw material - A material used in the primary production or manufacturing of a good. Raw materials are often natural resources such as oil, iron and wood. › Industrial Material – Produced from raw materials that have been reshaped or processed into standard shapes and sizes for production use.

 Anything used to make the materials assume the desired form.

 Any energy consumed to perform the work. › Electrical Energy › Heat energy › Human energy

 Includes the money, land, and equipment needed to set up and keep the system running.

 Includes the time required to build factories, make products, and ship products.

 All of the activities that need to take place for the system to give the expected result.

 Includes everything that results when the input and process parts of the system go into effect.  Intended Output – The product being produced.  Un-intended Output – Anything else such as waste.

 Feed back is the information about the output that is sent back to the system to help determine whether the system is doing what it is supposed to do.  There are systems without feedback. These are called Open Loop Systems.

 Impacts – Significant Effects  Can be positive or negative.  What are some positive and negative impacts of a cell phone?
